A common average changed beta correlation benchmarks under independent uniform contact phases in 19 SEEG records

We tested a contact phase model for adjacent bipolar beta correlation in 19 public SEEG records. The model retained contact magnitudes and drew independent uniform phases. A common average changed the model benchmark by a mean absolute 0.02076 correlation units. The descriptive 95 percent patient bootstrap interval was 0.01610 to 0.02569. The measured bipolar signals stayed unchanged to numerical precision. A proof shows why these two results can occur together. Checks for digital limits and nearly constant contacts gave a mean change of 0.02049. All 19 Fourier inputs were rebuilt from pinned public source ranges and matched exactly. The package contains code, data, source recipes, results, and instructions. The result applies to two minutes per patient, the specified beta bins, and the stated phase model. It does not measure brain connection prevalence.

    [Legacy relation: reproduces] We rebuilt all 19 inherited beta Fourier arrays from pinned public EDF ranges. All 4,222,800 complex64 coefficients matched exactly. This relation concerns the data extraction, not all results of that publication.

    We used its 19 Fourier inputs, patient selection audit, pinned source metadata, and EDF range recipes. We tested reference changes with a different contact phase model.

  3. usesMean beta correlation dimension was below the independent contact phase control mean after adjacent subtraction in 19 selected SEEG records sci:sha256:74c2f63797157b3350320d722b31801ba0b4dce7dd15d2a740e2ea313a6696bc

    Its independent contact phase model for bipolar beta correlation supplied the model context. We tested how a common source reference changes that model while observed bipolar channels stay unchanged.

    Its reference test showed that source power allocation can change while bipolar power stays unchanged. This result motivated our test of reference dependence in contact phase correlation benchmarks.

    We used its EDF parsing helper and the inherited record selection rules to check the public source data and rebuild the Fourier inputs.
